Dig It! The Secrets of Soil

Wall of soils at the Dig It! exhibit

There are more living creatures in a shovelful of rich soil than there are people on the planet. Yet, more is known about the dark side of the moon than about soil. These are just a couple of the fascinating facts visitors can learn at the traveling exhibition, “Dig it! The Secrets of Soil.” The exhibit's founding sponsor is the Soil Science Society of America (SSSA).

Dig It! is on exhibit at The California Museum in Sacramento, CA, through March 29, 2015, and will be in Raleigh, NC at the North Carolina Natural Sciences Museum from May 16 through August 16, 2015.




What is the "Dig It!" exhibit?

The 4,000-square foot exhibition reveals the complex world of soil and how this underfoot ecosystem supports nearly every form of life on earth. Developed by the Smithsonian's National Museum of Natural History with support from SSSA, “Dig It!” includes interactive displays, hands-on models, videos, and 54 soil monoliths representing soils from each U.S. state, territory, and the District of Columbia.

Its lead curator is Patrick Megonigal, a soil biogeochemist with the Smithsonian's Environmental Research Center and an SSSA member. Learn more on the Smithsonian’s "Dig It!" website.

In addition to funding from SSSA, the exhibit was made possible with generous support from Lead Sponsor, the Nutrients for Life Foundation, as well as Bayer CropScience, LI-COR Biosciences, Syngenta, and the U.S. Department of Agriculture.
